Application filed August 4, 1924. Seria1 No. 729,987.

To all whom it may concern Be it known that VALTEB f5}. BAKER, a citizenof the United States, residing at Norreal, in the county of Lancasterand State of Nebraska, has invented certain new and useful Improvementsin Drinking Cups, of which the following is a specification.

This invention relates to new and useful improvements in drinking cups,or containers for other liquids, the primary object of the inventionbeing to form a device of this character of few and simple parts,utilizing as a body therefor a section of an inner tube of an automobiletire, or any other tubular material may be adapted for this purpose.

Still another object resides in providing a device which may be termed acollapsible drinking cup, which may be quickly and readily set up foruse, collapsed when desired, and which may be improvised by tourists onthe road.

A. still further object resides in providing a device which is simpleand durable in construction, inexpensive to manufacture, and one whichis very effective in operation.

Other objects and advantages of this invention will become apparentduring the course of the following descript-ion.

In the accompanying drawing forming a part of this specification and inwhich like numerals designate like parts throughout the same,

Fig. 1 is an elevation View of the device.

Fig. 2 is a sectional view of the device cut by a vertical plane andFig. 3 is a sectional view of the device cut by a horizontal plane asindicated by the line 33 of Fig. 2.

Referring to the drawing, 1 designates a lower member consisting of anannular ring provided with heads 2 on the peripheral edges thereof andsecured within said annular member midway of its outer peripheral edgesis a bottom 3.

An upper member at is also provided similar to the member 1 having itsupper and lower peripheral edges beaded as shown at5.

These upper and lower members 1 and 2 may be stamped or otherwise formedfrom aluminum or other metal as may be desired and form the nucleus ofor substantially the frame work for a knock-down or collapsible drinkingcup.

The body of the cup is preferably formed of a rubber tubular section 6cut from a discarded inner tube of an automobile tire.

This section 6 may be of any desired height and in forming the upper andlower members 4: the same are stamped or formed so as to be slightlygreater in diameter than the inner diameter of the section 6. Of course,the members 1 and 1 may be formed in various sizes according to. thesizes of tube sec tions to be used in connection therewith.

In setting up the device as described the tube section of the rubberbody 6 is stretched over the outer periphery of the lower member 1 sothat one peripheral edge of said tube section will fit against onebeaded edge thereof, as shown in the drawing. The body andbottom of thecup are thus formed and in view of the fact that the bot-tom member 1 isslightly greater in diameter than the inner diameter of the tube of thebody section 6, these two elements will be snugly fitted together. Theupper member 1 is then applied to the other end of the tube or bodysection 6 by spreading the end of the latter around the periphery ofsaid member 4 until the adjacent edge fits against the one beaded edgeof said member. The cup is then complete and ready for use and it willbe seen that the members 1 and 2 form a. rigid frame work about whichthe cup may be constructed. It will further be seen that the cup may bereadily knocked down or collapsed by removing the upper and lowermembers from the body or tube section 6 and the device placed in somesmall convenient place in the automobile.

Tourists find it quite convenient to carry uiththem collapsible drinkingcups, but frequently they Inisplace the same or the usual drinking cupfound on the market is not satisfactory. By having the two end membersat hand, such as illustrated and described herein, a cup may be readilyformed by Cutting a section from an old or discarded innor tube. Eventhough the body or tube section used may be lostor misplaced, a. new cupnay be readily formed by cutting a section from an old tube.

While I have stated that this device is used especially as a drinkingcup, I wish itunderstood that it may be used for other purposes and I donot desire to be limited to its use as a drinking cup. Moreover, I havestated that the same is preferably made of material taken from oldautomobile tubes but, of course, I wish it understood-that it may bemade of tubular material other than automobile tubes.

It will be seen from the foregoing that I have provided a simple,inexpensive and efficient means for carrying out the objects of theinvention, and while I have particularly described the elements bestadapted to perform the functions set forth, it is obvious that variouschanges in form, proportion, and in the minor details of construct-ionmay be resorted to, without departing from the spirit or sacrificing anyof the principles of the invention.

Having thus described my invention what I claim is 1. In a drinking cupof the class described, upper and lower annular members provided ontheir upper and lower peripheral edges with beads, the aforesaid lowermember having a bottom formed midway of its outer peripheral edges, atubular elastic rubber body member removably applied to the outerperipheries of said annular members and having its upper and lowerperipheral edges abutting respectively the upper and lower beaded edgesof said upper and lower members, the lower beaded edge of the aforesaidlower member adapted to form a rigid base.

2. In a drinking cup of the class described, upper and lower annularmembers provided on their upper and lower peripheral edges with beads,the aforesaid lower member having a bottom formed midway of its outerperipheral edges, a tubular elastic rubber body member removably appliedto the outer peripheries of the said annular members and having itsupper and lower peripheral edges abutting respectively the upper andlower beaded edges of said upper and lower members, the lower beadededge of the aforesaid lower member adapted to form a rigid base, andmeans formed on the peripheral edges of said annular members at theinner opposed ends thereof for frictionally engaging the inner wall ofsaid body member to prevent casual disengagement of the latter from theannular members when the device is assembled.

In testimony whereof I affix my signature.

lVALTER S. BAKER.
